Enterprise Deployment: Disabling "Use Flash Player for playing 3D and multimedia content" in Acrobat

[Mpeterson9]

I'm attempting to find the RegKey associated with disabling and locking the "Use Flash Player for playing 3D and Multimedia Content" preference in Adobe Acrobat. This corresponds to the 20.013.20064 Planned update, Nov 03, 2020 version of the application.

Summary of Version/Category/Setting:

• Version (of Adobe Acrobat): 20.013.20064 Planned update, Nov 03, 2020
• Category: 3D & Multimedia 
  • Setting: Use Flash Player for playing 3D and Multimedia Content 
    • Disabled (enabled by default)

The only place I can seem to anything even semi-related to the setting is: HKEY_CURRENT_USER\SOFTWARE\Adobe\Adobe Acrobat\DC\3D

It appears to coorespond to the b3DEnableFlashPlayer REG_DWORD (screeenshot below):

These RegKeys are not created immediately following a successful installation. They are written upon opening the application > entering active Adobe Login credentials > then accessing the Prefrences menu (under the edit pulldown)

I've searched Adobe's Enterprise Registry/plist Reference but there are only options for enabling 3D content at this time.

Note:I understand that this is in the HKCU hive. Generally, these settings can be locked down in the HKLM hive. Specifically,  'HKLM\Software\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown'.

I've attempted adding the following entries within the 'Registry' area of Acrobat Customization Wizard, while configuring the MSI/MST but neither appeared to work following the installation 

• DWORD: b3DEnableFlashPlayer
  •  Value: 0
• Key name: c3D
  • DWORD: b3DEnableFlashPlayer
    • Value: 0

I am facing a similar issue, did you get any solution

You can disable by creating a registry key like this :[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\3D]
"b3DEnableFlashPlayer"=dword:00000000

It worked for me.
